Frankie B is Having a Sale!

That's a good reason to celebrate.

Los Angeles denim line Frankie B pioneered the ultra-low-rise super-sexy jean, which has garnered celebrity fans like Sienna Miller, Charlize Theron, Jennifer Lopez, Eva Longoria and Fergie.

If you, too, are a fan—and in Southern California this weekend--you’re in luck.

Frankie B founder and designer Daniella Clark is hosting two trunk shows this weekend at the Dungarees stores in Studio City and Calabasas.

There’ll be denim consultations, champagne, snacks and a “as a special, limited-edition gift with purchase.”

The party kicked off today and will continue tomorrow from 10 a.m. to 6 p.m. in Studio City at 12230 Ventura Blvd. and in Calabasas at 23555 Calabasas Rd.
